Consumer math help
denis23 [38]
<span>1. When you are paying a bill in full, said bill is completely paid off. In other words, the bill amount has been fulfilled by the consumer in a sort of payment. The answer is a. consumer is paying it off. 2. APR is a rate that is used frequently when applying and using a credit card. It stands for c. annual percentage rate or the percentage that will be charged when a credit card is not paid in full by the due date each month. 3. When calculating interest accrued you should multiply the principal by the APR & number of months, then divide the number of months in a year (12). This will be the interest that the consumer has gained and must pay off to the lender.</span>

Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fee
Llana [10]

Given :

Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile.

In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 .....1)

To Find :

How much did Hans pay for his trip.

Solution :

x = 450 miles.

Putting value of x in equation 1 we get :

y = $(0.17×450 + 15.89)

y = $(76.5+15.89)

y = $92.39

Therefore, Hans will pay $92.39 for his trip.

Hence, this is the required solution.

Solve for a.<br> 5 + 14a = 9a - 5
stira [4]

Since you are solving for a, you want to have a on one side of the equation and the other terms on another side of the equation. It would be easiest to have all the terms with a on the left side of the equation, so that is what we will do.

Subtract 9a from both sides to get a on the left side of the equation.

5 + 5a = -5

Subtract 5 from both sides of the equation to isolate the term with a.

5a = -10

Divide both sides of the equation by 5 to solve for a.

a = -2
